Ultra-Compact 3G/HD/SD-SDI Fiber Optic Micro Extender 120km
Overview
The LNK-M3G-SMB1V-20 Micro Extender delivers long-haul SDI and DVB-ASI transmission over a
single fiber link. Supporting resolutions up to 3G-SDI (2.97Gbps), it ensures broadcast-quality video with
ultra-low jitter, CWDM multiplexing, and simple plug-and-play setup. Its compact aluminum design and
low power consumption make it ideal for professional broadcasting, studio, and mobile production
environments.
